Recently, one of our research team members ran across an upside down tree. We talked about it and shared opinions about it with each other. Neither one of us have ever found one of these before. We both understand that other researchers have found numerous upside down trees and that they associate them with Bigfoot.
I also understand that sometimes logging companies do this, for whatever reason, but this was in an area were there was no logging and the tree did not appear to have any chainsaw marks.
Upside down trees seems to be an idea that has caught on pretty good in the bigfoot community, as something bigfoot does.
